You haven't by chance copied the ifcg-etho file to another file in the network-scripts directory, eg to save it whilst you played with it have you? I did this once and caused myself untold confusion because linux still used it. Other option is try pinging the problematic address - does it respond? If it does unplug each connection on your switch until you find the device causing it. If it doesn't ping then do the same but try using that address each time on your linux box and again you should find out what is using it. Might be something less obvious like a printer, it was last time I had this issue, I'd forgotten the printer was wireless.
